2027 Triumph Bonneville T40 Preview: Specs, Tech & NZ Launch
Triumph's highly anticipated Bonneville T40 has finally debuted, bringing the iconic Bonneville nameplate to its most attainable market position yet.
For many riders, the iconic Triumph Bonneville silhouette has long drawn their gaze as a must-own motorcycle. However, the price point of the T100 and T120 has often put these premium motorcycles out of reach, especially for those entering motorcycling with an eye for the definitive modern classic retro motorcycle.
Enter the 2027 Triumph Bonneville T40
Now arriving as something of a crown jewel in Triumph's incredibly popular TR-series of 400cc motorcycles is the Bonneville T40 (and T40 Black), bringing that iconic style and so much more to the class.
Triumph hasn't slapped a Bonneville aesthetic on the existing TR-series bikes to create the Bonneville T40, this bike sees the most comprehensive changes to the formula to date. A new frame, new wheels, new dash, a reworked engine, and of course, that oh-so-perfect Bonneville styling.
Starting with the obvious, Triumph has gone to great lengths to make sure that the Bonneville T40 looks like a Bonneville should. The fuel tank of the T40 looks like it could fit on any of its larger-capacity siblings, while the seat and twin rear shocks perfectly mirror the bigger bike's setup.
Triumph is launching the 2027 Triumph Bonneville T40 in three traditional two-tone schemes—Aegean Blue, Meriden Blue (above), and New England White—complete with hand-painted coach lines and classic spoked wheels (18-inch front, 17-inch rear).
If shiny chrome isn't your vibe, the T40 Black variant goes full stealth mode with Matt Pewter Grey and Matt Phantom Black paint, powder-coated engine casings, gloss-black rims, and a blacked-out peashooter exhaust.
The dash—often a point of contention with Triumphs—has received a massive hit with the upgrade stick. It’s now a 4-inch circular TFT display with full turn-by-turn map navigation powered by the new Triumph Navigation App (complete with GPX file import support).
Beyond the customisable riding modes (Road, Rain, Eco, plus 2 custom modes), Triumph has quietly packed in some genuinely thoughtful daily features—like a built-in USB-C socket, self-cancelling indicators, and an Emergency Deceleration Warning that flashes the rear light if you grab a handful of brake.
Built-in tech includes navigation, phone and music control, five riding modes (which let's be honest here, on a 400 might just be a little excessive), cruise control, lean-sensitive Optimised Cornering ABS and Optimised Cornering Traction Control. That adds up to some serious functionality and rider-assistance tech for the baby Bonnie.
Triumph has made big changes to the frame of the TR series for the new Bonneville T40. Gone is the monoshock arrangement we're familiar with from bikes like the Scramblers and Speed 400, and in its place, Triumph have reengineered the chassis to take a Bonneville-appropriate twin-shock arrangement.
In terms of ergonomics, it’s built to be as approachable as it is stylish. Sitting at a friendly 790 mm seat height (which can drop to 770 mm with an optional accessory seat) and weighing in at 191 kg ready-to-ride, it won't intimidate newer riders. Even better for DIY maintenance, Triumph has fitted a centre stand as standard (a huge win for chain-lubing duties) and backed it up with class-leading 16,000 km service intervals.
The Bonneville T40 and T40 Black are powered by the latest iteration of Triumph’s liquid-cooled 400cc TR Series engine. A revised cylinder head and dedicated Bonneville engine tune give the single-cylinder engine its own performance and character, combining modern performance and intuitive throttle response with the torque-rich delivery expected of a Bonneville.
Courtesy of a revised cylinder head and dedicated Bonneville engine tune, the T40 delivers increased torque lower in the rev range, with peak torque of 36 Nm at 5,000 rpm providing strong drive and a distinctive feel. Peak power of 32 PS is delivered at 7,000 rpm, placing the emphasis on accessible performance at everyday engine speeds.
I know what you're thinking: that's a decent chunk less than the Thruxton and Tracker have, and you're right. But the Bonneville is targeted at a different buyer who wants more feel lower in the rev range rather than outright top-end performance. Plus, delivering 32 PS keeps it fully LAMS legal straight out of the box, making it an incredibly accessible entry point to the Bonneville family. That power should be more than ample to get the Bonneville T40 up to highway speeds and beyond
And that's where the Bonneville T40 is quite different to the rest of Triumph's TR-series bikes. It's unashamedly targeting a different buyer than the somewhat mythical young hipster (who sadly for Triumph, appears to be an endangered species). Instead, the T40 is sure to be a hit with more discerning riders wanting that iconic Bonneville experience without the expense that comes with the T100 or T120 platforms.
The new Bonneville T40 and T40 Black are expected to arrive in New Zealand early in Q2 of 2027, with local pricing to be announced closer to launch.
